Item Description
Server Running State
• Enable—Enable the local SIP server.
• Disable—Disable the local SIP server.
By default, the local SIP server is disabled.
IP Address Bound to the
Server
Enter the IP address of the local server, which can be a local interface's IP
address, or a loopback address such as 127.0.0.1. The IP address of a local
interface is recommended because a loopback address cannot accept
registrations from remote users.
When the local SIP server is enabled, the IP address of the local server must be
provided.
Port Bound to the Server Enter the port number of the local SIP server.
Registration Aging Time
of the Client
Enter the maximum registration interval of clients.
Server Operation Mode
• Alone—The local SIP server in alone mode acts as a small voice server.
• Alive—The local SIP server in alive mode supports the local survival
feature. That is, when the communication with the remote server fails, the
local SIP server accepts registrations and calls; when the communication
resumes, the remote server accepts registrations and calls again and the
local SIP server rejects registrations and calls. In the alive mode, Options
messages will periodically be sent to the remote server.
By default, the local SIP server operates in alone mode.
